What they don't seem to understand is that in the fediverse it's them who are responsible for curating their own experience, there's no big content algorithm doing it for them here.

It's their job to join communities they may like and then set their main page to "subscribed". They don't have to keep it set in "ALL" if they don't want to see content from all the servers their server federates with/isn't defederated from.

Lemmy and kbin may be discussion platforms/link aggregators, but they aren't reddit.
